The dragon from the age of gods, about to die from the life or death battle with a human, and turned into an egg. Embracing her interest in the human that killed her, she asked her to protect her egg. The human gladly accepted.

The human got banished from the country.

The human, using the horn of the dragon, successfully created an elixir and became immortal (Unaging and undying). (This was over 1000 years ago)

The dragon incubated in the pseudo-space of Karindou's storeroom. Meanwhile, something strange happened in the storeroom, but because of it, they were completely unaware and neglected it for 8 years.

The dragon was rescued by everyone in Karindou once they realized something was strange, and was given the name of Ujikintoki Tamaryuu.

She's healthily growing. She's currently studying how to fit in with human society. (Right now)
